Osg 8599014 Screw Machine Drill Bit 0.055 in 130 Deg Xpm

Product Description

The OSG 8599014 is a screw machine length drill bit engineered for high-performance drilling in ferrous and nickel-based materials. Built from XPM high-speed steel with a coated finish, this bit delivers extended tool life in demanding production environments. It features a 130-degree drill point angle with X-thinned web geometry for reduced thrust and cleaner entry. The straight-cylindrical shank measures 3.00 millimeters in diameter, and the overall length is 41.00 millimeters (approximately 1.614 inches). It is sized at 0.0550 decimal inches, equivalent to wire gauge No. 54 or 1.40 millimeters. Machinists, tool and die technicians, and production drillers working in metal fabrication shops are the primary users of this tool.

This drill bit is suited for screw machine operations, production drilling, and precision hole-making in steel, alloy steel, cast iron, and nickel alloys. The screw machine length profile provides added rigidity compared to jobber-length bits, making it well-suited for CNC machine tools, drill presses, and screw machines where stub-length control is required. The 3xD flute-to-diameter ratio supports chip evacuation in short, through-hole applications without coolant-through capability required.

Key Features

• XPM high-performance high-speed steel construction with coated finish for extended wear resistance
• 130-degree split point angle with X-thinned, tapered web for reduced entry thrust
• Screw machine (stub) length for maximum rigidity in production drilling setups
• Right-hand cut, regular spiral flute design for standard chip evacuation in ferrous materials
• Wire gauge No. 54 sizing at 0.0550 inches with tight diameter tolerance of plus 0 to minus 0.014 millimeters
• Straight-cylindrical shank for direct chuck or collet holding without special adapters

Compatibility

Designed for use in steel, alloy steel, cast iron, and nickel alloy workpieces. Compatible with standard drill chucks and collets accepting a 3.00-millimeter straight-cylindrical shank. Part of the OSG Series 1900 screw machine length drill bit line.

Installation Notes

This tool is installed by machinists in CNC machining centers, manual drill presses, or screw machines. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the bit from the chuck or collet. Verify chuck or collet bore accepts a 3.00-millimeter shank before installation. Coolant-through is not supported on this bit; use external flood or mist coolant as required by the workpiece material and cutting parameters.
